What Glasgow Coma Scale (GCS) score indicates a minor brain injury?

A Glasgow Coma Scale (GCS) score of 13-15 indicates a minor brain injury. This range suggests that the patient is fully awake (in the case of 15), aware, and shows a normal response to stimuli. A GCS score of 13-15 is classified as mild because patients in this range typically retain the ability to follow commands, exhibit verbal responses that are appropriate or nearly so, and can open their eyes spontaneously or in response to stimuli.

In contrast, scores lower than 13 suggest moderate to severe brain injury, with reduced responsiveness and alterations in consciousness. This classification provides a crucial framework for evaluating the severity of neurological impairment in patients and guides further assessment and management in critical care settings.
